I recently (4 months ago) set up an HP200LX (1 Mb memory) for use by
people collection bird abundance observations from shipboard in
Antarctica. I was very impressed with it.
It's a little DOS machine, with a built-in copy of Lotus 1-2-3.
There's a layer of HP graphical software which can be disabled, saving
memory. You can repartition the 1 Mb of memory between program RAM
and RAM disk as appropriate for your use.
The unit is small and quite rugged. It has a small but usable
keyboard (not for touch-typing, but fine for data entry, particularly
if you set up useful one-key spreadsheet macros). It runs off two AA
batteries for several weeks.
Communications are over a serial port (signals are standard RS232, but
the cable connector is weird - buy HP's "Connectivity Kit", or build
your own cable and use standard old DOS serial communications
packages). It's also got a PCMCIA (PC Card) slot that can use memory
All in all, quite a useful little beastie. I recommend it -
particularly since it's now a model or two behind the most recent
releases, you can probably buy two or three used ones and have spares
(which is a MUST for field work).
